Brilliant service from start to finish. The team were tidy, punctual, and the finish is flawless. The new windows have made a huge difference to warmth and noise.
We went for a bespoke front door and it looks incredible. Communication was clear throughout and everything was measured and fitted with real attention to detail.
Top quality workmanship. Our cladding and trims are spot-on and the whole house looks sharper. Really impressed by how well everything was finished off.
Fast turnaround and great value. The install team were friendly and careful around the garden and interiors, and the new patio doors glide perfectly.
Couldn’t fault them. Accurate measurements, clean install, and a premium finish. We’ve already recommended SLJ to friends and family.
